Is the wife entitled to seek compensation from her husband for not having nights designated for her and for her privacy being affected due to her caring for her co-wife's children during the co-wife's travel?

A wife does not have the right to demand compensation for lodging during the period she cares for her husband's children from another woman. However, in return, she is not obligated to care for them unless she volunteers to do so. If she volunteers, she has done a good deed. It is not permissible for her husband's children to sleep in the same place as her if they are old enough to understand marital relations, due to the harm that could befall her, unless she consents to it.
